The objectives of this research are to study the production to find the proper ratio to test the physical mechanical properties and thermal conductivity to suggest the implementation and to transfer the technology of l ight-weight precast concrete wall panel product with aerated foam injection technique as core wall. The light-weight precast concrete wall panel product was produced by casting the mortar panels with M3 ratio (proper ratio) set up the steels and injecting the aerated foams. From the testing results followed the TIS.2226-2548 and TIS.878-2537 the general characteristic of light-weight precast concrete wall panel product was perfect. The properties of light-weight precast concrete wall panel product include 17.81 MPa of compressive strength no bending when installed in common behavior 11.38% of water absorption passed in type1 of hardness and impact test 1110.58 kg/m3 of density 9.18 MPa of bending strength and 0.186 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can use as the thermal insulation wall in building. the developing product can apply to register the petty patent.

The objectives of this research are to study the production to find the proper ratio to test the physical mechanical properties and thermal conductivity to suggest the implementation and to transfer the technology of light-weight precast concrete wall panel products mixed with container foam wastes. Design the ratios of Portland cement type1: coarse sand: lime stone: water equal to 1: 2: 4: 0.7 by weight and adding the container foam wastes equal to 0 0.025 0.050 0.075 and 0.1 by weight. Casting the light-weight precast concrete wall panel products by pouring the concrete into the mold which installed the steels. Test the properties follow TIS.2226-2548 and TIS.878-2537. From the results the proper ratio of adding container foam wastes was 0.075 by weight which had perfect general characteristic 16.48 MPa of compressive strength no bending when installed in common behavior 8.86% of water absorption passed type1 of hardness test passed type 2 of impact test 2014.54 kg/m3 of density 4.30 MPa of bending strength and 0.228 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can use as the thermal insulation wall in building. Moreover the developing product can apply to register the petty patent.

This research aims to study the usage pumice rock fragments to develop paving block product for community. The mixture ratios of Portland cement type1: sand: quarry dust: pumice rock fragments: water that there are 6 ratios. The paving block samples are casted in 30 x 30 x 5 centimeter in dimension. The paving block sample testing follows the TIS 378-2531 on concrete flooring tiles. From the experiment bending strength and thermal conductivity of paving blocks with high quantity of pumice rock fragments are lower than paving blocks with low quantity of pumice rock fragments but the water absorption of paving blocks with high quantity of pumice rock fragments are higher. However all of pumice rock fragments paving block samples with lower than 1: 2: 2.4: 0.6: 0.6 of ratio can pass the standard and the surface temperature is lower than other covering materials about 2 degree Celsius.

This research aims to produce scrap page kaolin of brick construction. The kaolin clay ratio of 100: 0 80:20 60:40 50:50 40:60 20:80 and 0: 100 by volume Add mixed with rice husk and rice 15 percent by weight A total of seven ratios. According to standard tests or TIS. 77-2545 ordinary story brick building. The moisture content and water absorption is increasing. While density Thermal conductivity resistance flexural and compressive strength tends to decrease. The best ratio of 80:20 by volume with compressive strength 43.16 kg / cm 2 and 24.93 percent water absorption. Criteria standard of TIS. 77-2545 requiring compressive strength not less than 35 kg / cm2 and water absorption must not be higher than 25 percent. Can be used in the manufacture of brick construction including building decorative wall can be developed into products. Because skin color and beautiful

This research aims to study how to use stones Pumice Products is interlocking block for community development. The mixture ratios of Portland cement type1: sand: quarry dust: pumice rock fragments: water that there are 5 ratios. The products were tested by the community TCPS 602-2547 (2004) (Thai): interlocking block. The results showed that interlocking block of stone pumice much a compressive strength and thermal conductivity under a block of stone pumice less. The water absorption is increased When a block of stone pumice much. The optimum ratio and the use of waste rock Pumice highest ratio of cement to stone dust on the stone Pumice water in a 10: 6.4: 0.6: 0.45 to 10: 6.1: 0.9. 0.45 by weight.
